Description of the SLM Technology
Short description of the Technology
Cultivation of tree belts across the direction of wind at appropriate intervals in the deposition zone, with a view to arrest wind erosion and facilitate stabilisation of dunes through interbelt development.
Detailed description of the Technology
The technology comprises establishment of 5 row shelterbelts at 160 m intervals. 3 row intermediary shelterbelts are introduced in between existing shelterbelts at 80 m interval. Land owners are encouraged to cultivate tree crops in between the belts.
Purpose of the Technology: Shelterbelts are useful in reducing wind velocity, there by arresting shifting of sand dunes, deposition of sand on fields, habitation, wells, roads etc. Cultivation of area between tree belts is made possible leading to increase in productivity from these lands.
Establishment / maintenance activities and inputs: The shelterbelts comprise tree species of different heights planted in rows (5 and 3 row deep) in a straight line across the wind direction. Six month old seedlings are planted in pits of volume 1 cuft to 1.5 cuft, which are filled with tank silt. One borewell is provided for one km length for life saving irrigation.
Natural / human environment: The environment is arid and forms the deposition zone wherein sand lifted from the impact zone is deposited. Sand dunes cover the area.
